module: pacman
short_description: Manage packages with I(pacman)
description:
- Manage packages with the I(pacman) package manager, which is used by Arch Linux and its variants.
version_added: "1.0"
author:

- Afterburn
options:
name:
description:
- Name or list of names of the packages to install, upgrade, or remove.
aliases: [ package, pkg ]
state:
description:
- Desired state of the package.
default: present
choices: [ absent, latest, present ]
recurse:
description:
- When removing a package, also remove its dependencies, provided
that they are not required by other packages and were not
explicitly installed by a user.
type: bool
default: no
version_added: "1.3"
force:
description:
- When removing package - force remove package, without any
checks. When update_cache - force redownload repo
databases.
type: bool
default: no
version_added: "2.0"
update_cache:
description:
- Whether or not to refresh the master package lists. This can be
run as part of a package installation or as a separate step.
type: bool
default: no
aliases: [ update-cache ]
upgrade:
description:
- Whether or not to upgrade whole system.
type: bool
default: no
version_added: "2.0"
notes:
- When used with a `loop:` each package will be processed individually,
it is much more efficient to pass the list directly to the `name` option.
